Specification of Letters Patent.

Patented April 13, 1909.

Application filed May 28, 1908. Serial No. 555,601.

T all whom it may concern:

Be it known that 1, DAVID A. GiLormis'r, a citizen of the United States,and a resident of Belgrade, in the county of Gallatin and State ofMontana, have invented a new and Improved Wagon-Jack, of which thefollowing is a full, clear, and exact description.

The object of the invention is to provide a lifting and supporting jack,whereon a wagon may be readily mounted and its wheels raised from afloor or the ground, and thus be free for removal for lubrication of thespindles that the wheels rotate upon and a further object is to soconstruct the lifting and supporting jack that it will serve effectivelyas a stock chute for a wagon.

The invention consists in the novel construction and combination ofparts, as is hereinafter described and defined in the,

appended claims.

nieference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a side view of the improvement with a wagon in sectionmounted thereon, and Fig. 2 is a transverse sectional view of theimprovement.

The body of the jack is formed of wooden planks, affording an oblongrectangular platform 10, that is strengthened by a plurality of sillswhich are secured by screws or bolts thereon, extending transversely onthe lower surface thereof.

other, side walls 11, 11, are erected and secured upon the platform orbottom wall 10, by means of upright batten strips 12, that wardly forsuch an engagement, and it is to be understood that any preferred numberof the sills and batten strips may be employed.

Upon the outer surface of the side walls 11 and resting upon the battenstrips 12 are trackway bars 13 which project above the side walls 11,and between each pair of batten strips an upright brace 12 is closelyfitted and secured u on the side walls 11, and upon the side wa ls 11,short braces 12 are positioned near the front ends of the said walls andsupported on one of the cross timbers 10 secured to the under face ofthe platform.

The track bars 13 are sloped on their upper f edges near their forwardends, and upon said edges, a wedge-shaped strip 13 is allixed, the widerend of each of said strips being disposed at the rear end of arespective track bar.

The braces 12 are lapped at their upper ends upon the traclrway bars 13,and said lapped portions are thereupon secured, thus providing a strong,durable connection between the side walls 11 and the trackway bars 13.The upper edges of the side walls 11 are sloped somewhat from the rearends of said side walls to the forward ends thereof, so as to correspondwith the sloped upper edges of the trackway bars 13, and upon the upperedges of each of said trackway bars, a metal facing strip a of strapiron or the like, is secured.

Upon each trackway har 13, at its outer side and near the rear endthereof, an ahutment piece e is secured, that projects upward and may beimpinged against the corresponding rear brace 12, so as to stiffen thepiece e. Forward of and near the abutment piece 6, on each trackway bar13, a prop brace g is pivoted near its center, the forward end of eachbeing slightly heavier than the rear end thereof, so that each bracenormally inclines forward and downward, and as shown in 1, a stop pin gis inserted in a respective traclrway bar, at a point near the forwardend of corresponding prop hrace, which limits the downward inclinationof the latter. At the side edges of the platform 10, that are parallelwith each When the device is in use the cross timbers 1O and 1C areseated upon a floor or level ground, which will dispose the forward endof the traclrway bars 13 slightly lower than y the lower sides of theaxles A of the wagon are arranged in pairs, each pair embracing the endof a slll 10 that 1s pro ected out- 1 a. The upper surfaces of the metalfacings on the traclrway bars 13 may be greased slightly and the wagonhe pushed either by hand or by a draft animal rearwardly, which willcause the axles A to ride upon the trackway bars. When the rear axleapproaches the abutment pieces 5, it will first depress the upper endsof the prop braces g, and then may contact with said abutment pieces.After the prop braces g are released oy the rearward movement of theaxle over them, said prop braces will resume their normal positions, andas shown for one prop brace in 1, the free upper ends of said braces gwill engage with the lower forward corner of the axle and receive thepressure of weight imposed by the tendency of the vehicle to slide downand forward on the trackway bars. The vehicle wheels are now raisedsufficiently from the ground, to permit their free rotation and may bereadily removed for lubrication of the axle spindles. Ohviously, afterthe wheels of the vehicle are replaced, the wagon may be slid down oilof the trackway bars 13, if the prop braces g are released from the rearaxle.

In order that the jack may he used as a stock chute for wagons and thelike, 1 provide the side walls 11 with hinged hoards 1 1 a forincreasing their width, and to the under side of the platform 10 at theforward end between two of the bars 10", I hinge legs 10, so that theforward end ol the chute can be elevated and arranged close to the openend of a wagon body. I also provide the upper surface of the platform 10with transverse cleats (l which serve as foot holds for the animals thattravel up or down the chute.

It is 01 course understood. that when the device is used as a jack, thehinged hoards l]? are turned down inwardly and the legs 10 are foldedunder the platform 10 as shown in Fig. 2.

Immaterial changes within the scope of the invention may lie made, and Iclaim all such alterations in form and proportions of the parts as arewithin the intent of the claims.

I claimgular platform, of a side wall erected along .1 g

each side edge of the platform, and having similarly sloped top edges, atrackway bar secured on the outer side of each side wall near the upperedge thereof, supporting oraces on the outer side of each side wall andengaging the trackway bars, metal facing strips on the upper edges ofthe trac-liway bars, an almtment piece on the outer side of eachtraclnvay bar, and a prop brace pivoted near its center on each traokwaybar so that its rear end will approach a corresponding abutment piece.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

DAVID A. GILCHRIST.
